Switch route processor (SRP) modules perform system management, routing table calculations and maintenance, forwarding table computations, statistics processing, configuration storage, and other control plane functions. Each SRP module is a PowerPC-based system with its own memory, nonvolatile disk storage, and power supply. (See Figure 9 and Figure 10.)
